While its sealed-case limitations will turn off power users, Apple's least expensive Mac delivers a solid OS X experience in a compact box with similar performance to the entry-level MacBook Air and iMac models.

Remaining the leader for intensive stylus input, the Microsoft Studio 2 seamlessly melds form and function for professional art and design. But it has a few weaknesses that might be deal breakers for people who need a lot of fast storage or more power.

Don't expect the world from HP's low-cost Pavilion All-in-One MS2255, but as a basic day-to-day PC for light-duty productivity or Web and media accessibility in the kitchen, it's a very good deal. You'd be wise to look here before considering an Atom-based Nettop.

Dell's XPS 430-121B, sold exclusively at Best Buy, outpaces the competition and carries an impressive set of media-centric features. Heavy gamers can find a more suitable system elsewhere, but digital media enthusiasts will appreciate this Dell in their home network.

Despite its good looks and a few useful new features, Apple's new iMac is all about business. You can find a larger screen for less, not to mention all kinds of digital entertainment features, but no other all-in-one at this price can boast similar performance. If you need a modestly priced all-in-one for getting work done, we'd recommend no other system.
